Replacing the Coralife disposable cartridge. I like the economy and ease of changing.

I have to shut off the water supply to my sink while changing out filters/ DI resin. Well, emptying out the DI cartridge can get a little messy... especially with no water to clean it up with. With the extra cartridge it becomes easy.

Well built and easy to use. This Cartridge is clear enough to see DI resin change colors to know when to replace it. Have used multiple times and still going!

Way better and cheaper than buying from manufacturer. It's the only way to keep tds at zero. Love it

Before replacing with this di resin, my ppm was 10+. The first cup of water through the new resin was 0 ppm. You would think that it would take a few gallons to run clean. Good stuff.

easy to use, works well. I bought a second one to make changing over even faster. That way I have one loaded and ready. You can get back to making water right away, cleaning out the expired one when you want.

Fixed my tds issue!! By Jameson 1/27/2014

James would recommend this product to a friend

I couldn't get my tds to zero. It was around 5 and was causing a phosphate issue in my tank. I replaced all my filters with brs filters and now my tds is zero!! With my savings I was even able to buy more spare filters. The di canister fit perfect in my coralife unit.

Good replacement for Coralife disposable.By Billon 1/22/2014

Bill would recommend this product to a friend

I picked up a used Coralife RO system for a great price. There was no difference in dissolved solids before and after the DI stage so I knew the resin was used up. Coralife uses a disposable cartridge, but I wanted a reusable canister. The BRS refillable 2.5 x 10 fits the Coralife just fine. I was not sure how old the other filters were so I replaced them with BRS filters. They all fit. My dissolved solids are now at zero. No more trips to the store to buy water.

every reefer should have a DI cartridge on hand in case the inevitable happens. This is a great quality replacement cartridge and much less expensive than buying pre-filled ones.

The product was on time, packed well. The housing seems much thicker than my last one, not from BRS, another well made product from the masters in REEFING. Thanks BRS!

Cartridge is quick and easy to refill. No reason to use disposable cartridges. Keep that junk out of the landfills.

Good stuff - wish it came with more sponges or..By Seanon 11/20/2012

Sean would recommend this product to a friend

These cartridges were very easy to fill and pack, and the sponges made for a perfect seal. I never thought I'd be filling my own DI cartridges, but for BRS' prices on these and the bulk DI resin (I chose color changing) vs. my RO/DI system "manufacturer" 's pricing for their pre-filled replacements, I figured I'd give it a try. If you are on the fence about filling your own, like I was, it's easy - just make sure you tamp the resin down and pack it plenty tight - NO FLEX when squeezing on outside of canister once assembled.

I wish the sponges were available to purchase separately though, and/or these came with more than 1 set - as I go to pull exhausted resin out, it sticks in the sponges, and they aren't quick to "decompress" to allow immediate refilling with the confidence you get the first time you use them. BRS? Does your supplier offer additional end sponges for these? Can you sell them?

Other than that, I've realized that my "top notch" 5-stage "system" was put together from what appear to be the very same parts available here, and I could have built identical performance for less. Oh well, you live and you learn.

I highly recommend this refillable cartridge, it beats throwing your money in the trash when you change those old DI cartridges. I also like the fact that you can fill them with the color changing resin.

This is a great upgrade to the one that I had in my RO/DI unit. The staff helped me on the phone pick this out and make sure it would work properly. With the new colored resin I can now have additional confidence in my water quality.

I got tired of spending so much for DI resin cartridges that I thought I would give this a try. It was so easy to install the resin that I wondered if I did it right. I am happy to say that I did do it right and my ro unit does not know the difference.

I bought one with the blue DI mix on my buddys last order and re packed my own this time, it was easy and didnt cost me $52.00 like last time i bought the whole unit at my local fish store. I highly recomend this to anyone and it fit better then the old one that came with my RO/DI..

I just recently setup my first 5 stage unit at home. I purchased this product along with the color changing resin and this is great. Turn off the RO unit once the TDS meter readings are over 0, replace the DI resin and put the unit back in. Easy to remove, change resin and replace!

Excellent way to save money on Di filtration! By Darrenon 5/25/2010

Darren would recommend this product to a friend

These canisters are easy to use. They allow you to buy bulk media and fill them yourself, saving money and at the same time wasting less because you are not throwing away all that plastic from non-refillable canisters. If you're paying $35 for preloaded, non-refillable, color-changing canisters, these things pay for themselves in one use! My water comes out as pure as always, so there's just no reason you shouldn't be using these.
